CULTIVATO R.

SPECIFICATION forming part of LettersPatent No. 296,025, dated April 1, 1884. Application filed January 27, 1883. (No model.)

To all whom it may concern:

Be it known that I, A. J. MARBERRY, of Cabot, in the county of Lonoke and State of Arkansas, have invented a new and useful Im- 1 provement in Cultivators, which improvement is fully set forth in the following specification and accompanying drawings,in which- Figure 1 is a perspective view of my im- 1 proved cultivator. Fig. 2 is a perspective IO View of a form of shovel. Fig. 3 is a perspec- V tive view of plow-fastening. Fig. 4 is a plan I View of Fig. 3, showing method of applying I the same. Fig. 5 is a perspective view of a form of single-tree clip. Fig. 6 is a perspec- I5 tive view of screw-threaded coupling-pieces,

plan view of beam, and side view of device.

The object of thepresent invention is to provide a cultivator consisting of two or more plows placed side by side and connected by means of rods, and arranged in such amanner as to beadjusted at any desired distance apart. By means of this arrangement rows maybe formed, ridges thrown up, and soil thrown to or from plants, as may be desired.

in construction to the ordinary plow-beam, provided at their forward ends with the clev ises O. The forward end of each of the beams is provided with a vertical slot, d, within which the clevis-boltOis placed. The rear end of I the clevis is secured, in the usual manner, by means of the bolt b. The slot cl permits the clevis to be removed by simply removing the bolt 1). The clevis-plates a are not connected I 3 5 at their forward end as in the ordinary clevis,

, but held together and in position by means of bolts, as shown in Fig. 6. The double-tree A is made of iron or any other suitable material, straight, if desired, but preferably with the central part curved upwardly. A series of oblong slots, a,are placed in the ends of the double-tree, which admit of a free lateral movement of the clevis-pins inguiding the plow. The single-trees D are formed in the I 5 usual manner, except the central clip, g,which is formed with a loop, having the ends far enough apart to clasp the double-tree, to which it is secured. The handle-shanks H are formed of any suitable material. The lower ends of the shear-beams are formed of metal, and secured to shank, as described, and slightly In the drawings, B are the beams, similar curved attheir lower extremity, E, the upper ends being provided with the usual handles, 17, while the lower ends lap over and have the upper ends of the shear-beams Esecured thereto, the said shear-beams resting within the oblique recesses h in the draftbeams B and secured thereto by means of bolts. A brace, F, extending through the beam B, connects with the shanks E below the beam.

. On the forward side of the handle-shanks H, and at some distance above the beams B,

are placed two screw-threaded pieces, I, each having on one side a bolt or stem, which passes loosely through a metallic plate, I, and is secured thereto by a tightly-fitting nut. These I metal plates, carrying the pieces I, are securely bolted to the said shanks, excavations having first been made in the anterior faces of the latter immediately in the rear of the pieces I. This arrangement admits of perfect freedom of motion of the pieces I in all directions. The outer beams, B, extend rearwardly somewhat, and are provided with metallic shanks secured by means of a nut on the lower side.

Excavations should be made in the shank H immediately in the rear of the pieces I, to admit of free play of the pieces in all directions, and all the openings through which they pass should be of such asize as to admit of perfect freedom of motion of the pieces I in all directions, sothat the plows may be easily guided, and that either side of the cultivator may move in advance of the other without causing any cramping or stiffening of any of the parts. Gage-rods J are provided, having right and left hand threaded screws at the ends which extend laterally through the pieces I. By turning these rods either backward or forward, as may be desired, the distance between theplows can be increased or decreased. The central placed at the center of one of the rods, provided on one side with a hook, 1*, which connects with the other rod, and thus prevents them from turning.

Fig. 2 shows a form of sweep or shovel that can be used with this cultivator for particular kinds of work. One of the sides or wings is made very short, while the other is of ordinary length. When the cultivator is used with four plows, and it is necessary that those next the plant be broad and short, this form is indispensable. If both wings were long, the outer ones would extend out in front of the middle or breaking plows, and cause them to choke up with trash. \Vhen two plows are used, and. it is desired to do close deep work near the plants, this form of shovel, with its short wing turned toward the plant, is desirable.

A form of fastening to be used. at the bottom of the shank to secure the shovel is shown in Fig. 3, in a yoke of which the sides i are formed parallel to receive the shear-beams. The ends are provided with lateral flanges or seats j, through which openings j are placed. The shovel m, Fig. 4, is placed forward of this, with the concave next the shank Z, and secured in position by means of the bolts n. The object of the yoke i on the shank is to enable the concave side of the shovel to be secured thereto, and by releasing the bolt on one side and taking up the other theshovel can be turned so that the soil may be thrown to either side, as described. If desired, the outside plows can be removed altogether for particular kinds of work by removing the forward clevis-pins and unscrewing from the gage-rods.

As will be seen, the plows can be placed at any distance apart by turning the gage-rods backward or forward and changing the clevisbolts to different openings.

WVhat I claim as new is 1. In a cultivator, the device for securing the shovel to the shank and holding it in any desired position by means of a yoke, z, bent around the shank from the rear, the forward ends provided with wings or flanges to receive L the concave side of the shovel, and secured by means of bolts, andarranged for throwing the soil either to the right or left, substantially as herein set forth.

2. The combination, in a cultivator, of the yoke, the adjusting holes and bolts, and the shovel arranged on the shank so as to rock thereon laterally and adj ustvertically, as and for the purpose substantially as herein set forth.

3. The combination of the gage-rods J J,

bowed centrally to be used as cranksin moving the plows inwardly or outwardly, as desired, with the ring and hook to secure said rods in position, substantially asherein set forth.

- 4. The combination of the eyebolts pro vided with stems, as shown, and the plates G H, with the gage-rods having right and left hand screw-threads, substantially as herein set forth.

5. The combination, in a cultivator, of a double-tree, A, provided at each end with a series of oblong slots, the central part bowed as described, and the clevis formed of two plates connected by means of bolts to the beam,with the plates GH, the eyebolts I, and the gage-rods J, the whole arranged and combined substantially as herein set forth.
